Nhv.Org was originally designed in 2010 when it was noticed that many people were using the tag #NHV. This was in order to mention "New Haven" online, and was part of a national trend of using the customary abbreviations of airport or train codes to mention a city within the confinement of Twitter's 140-character limit. New Haven's tag became #NHV and everyone from Yale to the City of New Haven's official accounts have used #NHV as a way of sharing information to a locally interested audience.
